摘要

PROBLEM TO BE SOLVED: To provide a photo-magnetic flux converting element which can record two-dimensional light signal good. SOLUTION: A photo-magnetic flux converting element 10 is provided with a plurality of anti-dot 5 for capturing (pin-keeping) stably magnetic flux quantum generated by a superconductor 2. Therefore, the photo-magnetic flux converting element 10 holds a picture (magnetic flux picture) by magnetic flux distribution of which one pixel is each anti-dot 5. Therefore, in the photo- magnetic flux converting element 10, pixel density can be improved by arranging anti-dot 5 in which density. Thereby, the photo-magnetic flux element 10 can convert a light signal expanded two dimensionally to magnetic flux picture with high resolution. Therefore, the photo-magnetic flux element 10 can record a two dimensional light signal good.
